Now it's time for our collaboration with the awesome What Is It? Blog! What is this thing? You don't have to know to win!

Place your guess in the comment section below. One guess per comment, please, though you can enter as many as you'd like. You might know the true answer, but we're going to select two winners who come up with the funniest, most outlandish guesses to win a T-shirt from the NeatoShop. However...

Update: the mystery item is a bread slicer. Using a knife and this device you can make a 1/2" thick slice of bread into two 1/4" thick slices. Why you would ever want to do that is beyond me. But we were looking for funny answers and we got them!

Carlos Pfister had a funny one: "Thats a Decepticon Pop Tart. It transforms into a mean little bastard." Another good one came from mowog, who said: "It's a cheese 'Swisser.' Insert cheap, plain white cheese, puncture - PROFIT!" Both win a t-shirt from the NeatoShop for those answers! See the answers to all of this week's mystery objects at the What Is It? blog.
